VACUUM CLEANER ATTACHMENT FOR A HAIR CLIPPER Filed Sept. 27, 1965 1" fillin Arme/VEYS United States Patent 3,348,308 VACUUM CLEANER ATTACHMENT FOR A HAIR CLIPPER Matthew G. Andis, Racine, Wis, assignor to Andis Clipper (30., Racine, Wis., a corporation of Wisconsin Filed Sept. 27, 1965, Ser. No. 490,338 2 Claims. (Cl. 30133) This invention relates to a Vacuum cleaner attachment for a hair clipper.

It is contemplated that otherwise conventional hair clippers of the type in which the case mounts blades and also serves as a handle may be equipped with vacuum cleaner nozzles which are complementary to the casing substantially corresponding thereto in width and adding only slightly to the height so that the nozzle and the clipper case together will thenceforth constitute the handle.

Two different embodiments are disclosed. One of them is intended to replace completely the cover normally provided for an opening in the top of the case. In this embodiment, a transverse partition across the opening left by the removal of the cover completes the passage through which the vacuum withdraws the clippings from the vicinity of the blades. In the other embodiment herein disclosed, the top of the casing serves as a floor for the nozzle passage. Thus no partition is required.

In both embodiments, a vacuum hose connection is provided at one end, and the other or inlet end opens in immediate proximity to the clipper blades.

In the drawings:

FIG. 1 is a view in side elevation showing a conventional hair clipper equipped with a vacuum nozzle in accordance with the present invention, portions of the nozzle being broken away.

FIG. 2 is a plan view of the device shown in FIG. 1.

FIG. 3 is a view in rear end elevation of the device shown in FIG. 1.

FIG. 4 is a view in front elevation of the device shown in FIG. 1.

FIG. 5 is a view in transverse section on the line l5-5 of FIG. 2.

FIG. 6 is a view similar to FIG. 5 showing a modified embodiment in which the nozzle substitutes for the cover with which the clipper casing was originally provided.

The hair clippers shown are of generally conventional construction. In the embodiment of FIGS. 1 to 4, the complementary casing elements 8 and 10 enclose the usual motor which reciprocates the cutter 12 on shear plate 14, the latter being fixed to the lower housing element 8. At the rear end of the casing there are electrically conductive prongs 15 for the attachment of a conventional extension cord. A slide 18 on the side of the casing controls the motor switch housed therein.

According to the present invention, a vacuum nozzle 20 is made in a form which is complementary to the top of the clipper casing. In cross section, the vacuum nozzle 20 may constitute an inverted channel as best shown in FIG. 5. It is seated on the top section 10 of the casing, being shouldered at 22 to embrace the corners of the casing section 10. The interior channel 24, somewhat ice flattened at its forward end 26, terminates in immediate proximity to the cutting blades from which the low pressure within the channel withdraws the clippings.

The nozzle 20 is closed at its rear end by a transverse wall 28 through which opens the tubular connector 30 for attachment of a vacuum hose. The vacuum hose of a conventional vacuum cleaner may be used if desired. The integral tube 30 may be regarded for the purposes of this disclosure as a coupling for connection to a vacuum line of any sort.

Optionally, a groove 32 may be provided about all margins of the nozzle which are desirably sealed to the top section 10 of the clipper casing. The mere provision of the groove will ordinarily suflice but packing material may be placed therein if desired.

The screws used to connect the upper and lower sections lit and 8 of the clipper casing may be replaced by somewhat longer screws 34 which will hold the nozzle to the casing as a part of the unitary clipper handle assembly.

If the casing is one which has a removable top plate seated in shoulders such as those shown in FIG. 6 at 36, the nozzle attachment may be designed to fit these same shoulders and may have side walls 38 and 40 which are respectively continuations of the side surfaces 42 and 44 of the clipper casing. In this event, the nozzle 200 may be partitioned to provide an internal passage 240 leading to a vacuum coupling 30 just as above described. The cover of the clipper casing being absent, it is desired that the nozzle have its own floor or bottom partition wall 46 as shown in FIG. 6.

I claim:

1. The combination with a hair clipper having coacting blades and a supporting casing which constitutes a handle upon which the blades are mounted and by which they are guided and which comprises separable parts held together by screw threaded connectors, of a vacuum nozzle extending across the top of the handle and having an open mouth proximate the blades and having its rear end provided with a vacuum connection, said vacuum nozzle being attached to the casing by the same screws which connect the component parts of the casing to each other the vacuum nozzle having the form of an inverted channel having a lower margin with a peripheral shoulder and depending flange complementary to the top of the casing and closely fitted thereto, said shoulder and flange providing a sealed connection between the casing and nozzle, the nozzle coacting with the casing as a part of the handle by which the clipper is manipulated in use.

2. A combination according to claim 1 in which the nozzle is substantially coextensive with the casing and the depending flange embraces the casing externally.
